Document Summary
Chapter 4: the structure and electrical activity of neurons. Dendritic spines branches and small protrusions that increase a dendrite"s surface area. Axon hillock a single axon that extends out of the cell body. Axon collaterals branches of an axon, which, usually emerge from at right angles. Teleodendria smaller branches that are divided by the ends of axon collaterals. Terminal button (end foot) knobs that are found on the ends of each teleodendrion. Synapse the space between one axon"s end foot and the neighboring dendritic spine. Neurotransmitter chemicals that carry a message across the synapse and increase electrical activity of the target. Proteins complex organic compounds, including enzymes hormones and antibodies that form the principle components of a cell. Nucleus an organelle that stores and copies a cell"s proteins (genes and chromosomes) Endoplasmic reticulum (er) folded layers of membrane where proteins are assembled. Golgi bodies membranous structure that packages protein molecules for transport.
